Scavenger Hunt: 46-50

50. Endosperm

Endosperm is the tissue produced in the seeds of most flowering plants. It is the tissue containing stored food in a seed that surrounds the embryo and is eventually digested by the embryo as it grows at the time of fertilization.

49. Xylem

Xylem is the wood of a tree, made up of strong fibers, tracheids and vessels. It is vascular tissue designed to help transport water and minerals from the root to the leaves. This is a picture of the bottom of a tree. Xylem helps this tree's leaves recieve enough water.

48. Rhizome

A rhizome is a horizontal underground stem, with leaves and buds, that serves as a storage organ and a means of vegetative propagation. It is a horizontal underground stem of some plants that sends out roots and shoots from its nodes.

47. Biome

This is a picture from Shelter Island. Beyond the water is a forest, which is an example of a biome. A biome is aliving community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region. Biomes include: permanent ice, mountain, desert, grassland, scrub forest, chaparral deciduous forest, taiga, and tundra.

46. Radial Symmetry

This lemon is a picture of radial symmetry. Radial symmetry is a form of symmetry in which the parts of an organism are arranged concentrically around a central oral/aboral axis and more than one imaginary plane through this axis results in halves that are mirror-images of each other.
